Whenever I render this model, the surface looks all screwy with black lines and blocks. As far as I know, I’ve deleted all of the materials, but the same thing still happens when I render the image. I can’t figure out where this weird pattern is coming from. I’ve even tried importing the object into a new blend file, but whatever is causing this stays with the model. Any help would be much appreciated.
